Research On The Landscape Design Of Urban Parks Adaptable To Rainwater And Floods Based On Elastic Landscapes

In recent years,with the rapid development of urban construction,accompanied by the frequent occurrence of global climate change and extreme weather,the coping ability of traditional urban parks has become slightly weak,resulting in frequent waterlogging and serious disaster losses in landscape construction.Since its birth,the concept of elastic landscape,which has focused on enhancing the adaptability of landscape systems to deal with external disturbances and changes,is a clear and effective choice.Therefore,this paper takes the elastic landscape as the theoretical support,adopts the method of field research,literature research,case analysis,analytic hierarchy process and inductive summary method to carry out research on the rainwater adaptive landscape design of urban parks.This research is mainly divided into three parts,namely comprehensive theoretical research,data and information evaluation analysis and strategy research,and planning and design practice.First of all,the theoretical comprehensive research part sorts out the relevant concepts and theories such as "resilient landscape" and "adaptation to rain and flood",and combines the relevant research progress at home and abroad,and summarizes the integration of "resilience",a new perspective of landscape architecture,into the city.It is necessary to improve the adaptability of rain and flood in park planning and design;secondly,on the basis of theoretical research and case analysis,this study discusses and optimizes the landscape planning and design of urban parks adaptable to rain and flood from the perspective of disaster-pregnant environment and disaster-bearing bodies and management process,build a stormwater disaster risk assessment framework,and take the research site as an example to carry out its stormwater disaster risk assessment,and then summarize 9 design principles and 6 design strategies;finally,the above theoretical research is applied to planning and design In practice-In the landscape planning and design of Shenzhen Dameisha River Park,a complete design scheme is formed,and the preliminary analysis of the site,design goals and strategies,overall design,rainwater adaptability planning and design,and special planning and design are mainly introduced.Among them,the design strategy is proposed based on the visualization analysis results of ARCGIS software after the risk assessment of rain and flood disasters and the analysis of the current situation of the site.At the end of this study is the summary and discussion of this study,the specific conclusions are as follows:(1)It is a necessary choice to integrate the new perspective and new thinking of "resilience" into the discipline of landscape architecture.Whether the main body is a city or an urban park,improving its elasticity will bring results from multiple aspects and levels.(2)Reducing the risk of disaster-pregnant environment and the sensitivity of disaster-bearing bodies in urban parks is the most direct way to enhance their adaptability to rain and floods and reduce disaster losses.(3)Landscape architecture,as a comprehensive discipline with breadth,should try to combine it with other software and analytical methods,which will enable learners to experience new gains and new depths.(4)After the planning and design are supported by data analysis,the design focus will be clearer,the strategy will be more targeted,and the research will be more convincing,verifying the necessity of planning,design and management process optimization in practice.This paper provides a certain theoretical reference for the research on elasticity-related theories,and provides new ideas and management optimization strategies for the planning and design of urban park landscapes adaptable to stormwater and floods,and has certain reference value for the ecological landscape design of other urban parks.
